" TED STATES PATENT JOHN C. SPROULL, OF LAWRENCE, KANSAS.

AcnTYLnNn-Gas GENERATOR.

Application ledJuly 30, 1915.

To all whom t may concern:

Be it known that I,-JoHN C. SPROULL, a citizen of the United' States, residing at Lawrence, in the county of Douglas and State of Kansas, have invented new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

Thisinvention relates to improvements in acetylene gas generators.

In carr in@` out the resent invention it is my purpose to provide an acetylene gas generator wherein an auxiliary carbid con by eliminating slaking of the carbid in the container and avoiding clogging of the valve controlling the flow of carbid from the container to the generating tank.

Another object of my invention is to provide an acetylene gas generator wherein the gas will be filtered previous to leaving the generating tank and the moisture removed therefrom and discharged back into the generating tank, thereby preventing the wet gas from entering the burners or other gas consuming devices.

A further object of my invention is to` provide a generator of the class described wherein the auxiliary carbid container'may be manually operated from the exterior of the generator to discharge the contents thereofy into the main carbid container and wherein the discharge of the carbid from the auxiliary container to the main container will be such as to prevent the loss of the carbid, incident to such carbid flowing through the open valve of the main container into the water in the generating tank.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

acetylene gas generator constructed in accordance with the present invention. F ig. 2 1s an enlarged fragmentary vertical sectional view through the generator showing the auxiliary carbid container and controlling mechanism therefor.

Referring now to the drawings in detail, 1- designates a generating tank of any desired capacity and having the lower end closed and the upper end` portion circumferentially reduced to form a neck 2. In the present instance, the upper end of the neck 2 is open and disposed withinthe tank 2 is a main carbid container 3 in the form of a hopper and the upper end of the side wall of the hopper-shaped carbid container 3 is flanged outwardly as at 4 and the marginal edge of the flange secured to the upper edge of the neck 2, thus closing the neck of the generating tank. The lower portion of the generating tank 1 is designed to contain a quantity of water 5, while the carbid container 3 is adapted to hold a quantity of carbid 6. The lower end of the hoppershaped container 3 is equipped with a controlling valve 7 controlling the flow of carbid from the container 3 into the tank l and the disk of the valve 7 is equipped with a stem 8 projecting upwardly through the carbid container 3 and having` the upper end thereof terminatingv above such container. Closing the upper4 end of the carbid container 3 is a cover 9 resting upon the flange 4 and formed centrally with an opening through which the upper end of the stem 8 passes, while formed on the cover 9 concentrically of thestem 8 and surrounding the latteris a sleeve 10 having the lower end formed with a protector or shield 11 conical in shape and spaced apart from the bottom of the hopper-shaped container 3. This shield 11 supports the 'weight of the carbid within the container 3 so as to prevent such carbid from exerting undue pressure on the valve 7. Surrounding the neck 2 of the generating chamber and spaced apart therefrom concentrically thereof is a circular shell 12 having the lower end suitably secured tothe generating chamber at the juncture of the neck with the bottom portion of such chamber. Disposed vwithin the space between the neck 2 and the shell 12 is a quantity of oil, kerosene, water or analogous sealing material 13.

14 designates a bell having the side wall thereof immersed in the liquid 13 and capable of vertical movement therein, and the top end wall overlying the upper ends of the neck 2 and the hopper-shaped container 3.

In accordance with my present invention, the neck 2, adjacent to the upper end thereof, is formed with a circular row of openings 15 establishing communication between the tank 1 and the bell 14, while mounted with in the tank 1 below the container 3 is an appropriate form of gas filter 16.

Connected with the lower end of the filter 16 yand extending out through the side wall of the tank 1 is a supply pipe 17 leading to the burners or other gas consuming devices, while connected to the pipe 17 below the ilter 16 and extending down into the volume of water 5 in the tank 1 is a drain pipe 18 through which the moisture extracted from the gas by the filter 16 is discharged back into the water 5 in the tank.

Secured to the bottom end wall of the tank 1 andrin open communication therewith is a drain pipe 19 equipped with a cutoff valve 20 and leading to a suitable sewer or other place of drainage. The drain pipe 19 is employed only where the drain water I may be discharged by gravity into the sewer, while in localities where no draining facilities are present, a pump 21 is employed. This pump is located at the desired elevation and connected by means of a depending vertical pipe 22 with the drain pipe 19. l/Vhen the valve 20 is opened and the pump 21 placed in operation, the refuse is pumped, out of the bottom of the generating tank 1.

In practice, when the gas bell 14 is lowered, such bell engages the upper end of the stem 8 and opens the valve 7 and when the valve 7 is opened, the carbid feeds from the carbid container 3 into the water 5 in the tank 1. As the carbid enters the water the gas is generated and such gas flows up? wardly around the container 3, through the openings 15 into the bell 14, thereby elevating the bell and in the upward movement of the bell the stem 8 is released and the valve 7 closed by the pressure of the gas on the under side of the valve, thereby cutting off communication between the'carbid container and the tank. When the burners are in service the gas fiows from the tank 1 through the filter 16 and the pipe 17 and as the gas is consumed the bell lowers and again opens the valve 7 so as to generate the gas in accordance with the consumption thereof. As the gas passes through the filter 16, the moisture is extracted therefrom and the condensation is restored to the water 5 through the drain pipe 18.

Mounted within the main carbid container 3 and suitably fastened to the side wall thereof adjacent to the upper end of such through the incline portion of the tank 1 that connects the neck 2 with the botte-ni portion of such neck. This upwardly. extending portion 27 of the rod is surrounded by a tube 28 that projects down into the water 5 in the tank so as to prevent the escape of gas from the generating tank. The upper end of the portion 27 of the rod'26 is equipped with` a ring29. lVhen it is necessary or desired to release the contents of the auxiliary container 23 so that such contents will be discharged into the main carbid container 3, the ring 29 is pulled upwardly, thereby elevating the rod 26'and in the upward movement of the rod 26 the arm 25 pulls the chain 24, thereby tilting the swinging bottom of the auxiliary container. In the initial upward movement of the rod 26, the bottom ofthe auxiliary container is swung to discharge a small quantity of the contents thereof into the main containerv and, assuming the gas bell 14 to be in lowered position and the valve 7 open, such quantity of the carbid from the auxiliary container will flow into the water 5, thereby generating sufficient gas to elevate the bell 14 to close the valve 7, and in the continued upward movement of the rod, the bottom of the auxiliary container is swung to discharge all of the contents of such container into the main container and as the valve 7 is closed, the carbid is held inthe main container and discharged therefrom in the operation of the valve 7. n

While I have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not. limit or confine myself to the v precise details of construction Vherein described and delineated, as modification and variation may be made within the scope of the claim without departing'from the spirit of the invention.

I claim: s
